Intravascular ultrasound versus angiography for measurement of luminal diameters in normal and diseased coronary arteries.

abstract：BACKGROUND:Drug-eluting stents have been shown to reduce restenosis in many types of lesions. The purpose of this article is to assess the efficacy of sirolimus- and paclitaxel-eluting stents in patients with bifurcation lesions. METHODS:Between June 2003 and October 2004, 205 patients were enrolled in a prospective r...
